The Hand provides security in Spider-Man: Brand New Day. The Hand is a group of ninjas previously associated with Marvel's Netflix-era television stories.
In the film, the head of the Department of Damage Control, Bill Metzger, uses the Hand for security. Spider-Man also fights members of the organization as he protects New York from street-level threats. Their return links the film's story to the wider Marvel television continuity.
The Hand is distinct from organizations such as HYDRA and the Ten Rings. Those groups have different histories, memberships, and goals within the MCU. Brand New Day uses the Hand as part of its grounded criminal and security plot, alongside characters including Scorpion, Tombstone, and the Punisher.
